Description
Technical field
The utility model relates to a kind of synchronous surface dressing car pitch combination valve that is used for the loop control of synchronous surface dressing car pitch.
Background technology
At present, the pitch loop control of synchronous surface dressing car is mostly adopted manually or Pneumatic butterfly valve changes the circulation path of pitch in pipeline and realizes, in whole pitch loop control process, owing to need a plurality of valve combination to control, the structure configuration is complicated, troublesome poeration.In addition, because working media is the very high pitch of viscosity, if at the untimely cleaning pitch pipeline in back of finishing the work, butterfly valve just is easy to occur replying phenomenon not in place, causes to occur the problem that butterfly valve is not closed completely, pitch is revealed in the equipment circulating system.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provide a kind of structure configuration simple, easy to operate, can effectively avoid not revealing, and be convenient to realize the synchronous surface dressing car pitch combination valve of pitch circulating system automation control because of valve closing does not sternly cause system pitch to occur.
The technical scheme that realizes above-mentioned purpose is: a kind of synchronous surface dressing car pitch combination valve, and it has the box valve casing that is separated into two valve pockets by the intermediate section dividing plate, and an end of this box valve casing connects the pitch suction flange, the capping of other end assembling end; On the box valve casing, be connected and be provided with the pitch floss hole with the valve pocket that is connected the suction flange side, pitch advances the spray bars valve port and valve pocket is communicated with valve port, hold the valve pocket of capping side to be connected with assembling and be provided with another valve pocket connection valve port, pitch goes out the spray bars valve port and connects the asphalt tank valve port, advance the spray bars valve port with pitch, pitch goes out the spray bars valve port, connect the asphalt tank valve port and be communicated with one of them valve pocket that valve port is corresponding to be respectively fitted with cylinder on the lateral surface of box valve casing, the piston rod of each cylinder stretches in the valve pocket and is respectively fitted with the valve port plug that matches with relative valve port; The lateral surface of box valve casing is provided with and is communicated with the bridge tube that two valve pockets are communicated with valve port.
The technical solution of the utility model also comprises: the convex globoidal that cooperates with valve port is arranged at the top of described valve port plug; Be provided with the conduction oil torus in the both sides of box valve casing, be communicated with the conduction oil torus and be provided with the conduction oil import and export.
The beneficial effects of the utility model are: adopt combination valve, the structure configuration is simple, handled easily, be convenient to realize the automation control of the pitch circulating system, and convenient cleaning to circulating system pipeline is avoided depositing the stagnant Control Failure of bringing and the generation of pitch leakage phenomenon by pitch in the circulating system pipeline; The valve port plug adopts convex globoidal valve port sealing structure, good seal performance, reliability height; In the both sides of box valve casing the conduction oil torus is set, has in the time of can guaranteeing pitch through combination valve and stablize suitable temperature, and have the configuration structure characteristic of simple.
